The object of our invention is to provide a novel and usefulweatherproof steel basement sash of novel construction as hereinafterdescribed. We attain the objects of our invention by the deviceillustrated in the accompanying drawings, in which,-

Figure 1 is a front plan view of the metal sash and frame viewed fromthe inside;

Fig. 2 is an edge elevation of same;

Fig. 3 is a longitudinal section on line 3-3 of Fig. 1;

Fig. 4 is a detail perspective view of a corner of the sash and frameillustrating the sash lock on an enlarged scale;

Fig. 5 is a plan view of the outside of the sash and frame;

Fig. 6 is a transverse section on line 6-6 of Fig. 5; and- Fig. 7 is anend elevation with the sash in open position.

Like numerals designate like parts in each of the several views.

Referring to the accompanying drawings, we provide a metal window framecomprising the head jamb I, sill 2, side jamb 3, and opposite side jamb4. We provide suitable brick and tile stays 5 welded on the side jambsas shown in Fig. 3.

As shown in Fig. 6, the sill 2 is bent longitudinally at 6 and has theoutwardly curved portion I. We provide a curved Weatherstrip 8 welded tosill 2 as shown in Fig. 6. We provide suitable hinges for hingedlymounting the window sash on the head jamb of the window frame. In thedrawings, there are illustrated brackets 9 of head jamb I, hinges II,and brackets III in which the lower ends of hinges -I I are slidablymounted. We provide a coil spring Ila on hinges II disposed between thespaced brackets III, the spring being secured to the hinge at the outerend by a suitable pin or the like to provide an eflicient spring hinge.Hinges II are of T-shape as shown.

We provide a window sash comprising a metal top rail I2, metal bottomrail I3, metal end rails I4 and I5, and metal muntins I6. Members I2,I3, I4 and I5 are L-shaped in cross section.

We provide suitable guides IT in which are slidably mounted suitablelocking bolts or catches I8 pivotally attached at 22 to catch operatingmembers I9 which in turn are pivotally mounted by member 2| on the sashrail I3. We provide apertures 23 in the side jambs 3 and 4 to receivethe bolts I8 to lock the sash in closed position. We provide a suitablehandle 24 for the sash.

As shown in Fig. 6, we provide a curved weatherstrip guard 25 extendinglongitudinally of the sash and forming the bottom thereof as shown inFig. 6 and of similar curvature in cross section to the curvature of theWeatherstrip 8 with which 5 it snugly contacts when the sash is inclosed position. We provide a suitable glass pane 21 which is held inplace by putty 26 and other suitable means.

We provide a Weatherstrip, depending from 10 head jamb I. We provide ascreen 33 mounted in the screen frame members 29 and 3|. Screen framemembers 3| are fastened in place on V- shaped weatherstrips 30 by meansof bolts 32, as shown in Figs. 3 and 5. 10

The Weatherstrip extensions 30 have their ends slanted or beveled, asshown in Fig. 6, to allow the sides 25 and 34 of the window frame toseat snugly in place, as shown in Fig. 6 and Fig. 3, with members 25 and8 in abutment and with said Weatherstrip extensions 30 overlapping theend puttied portions 26 of the window frame, said puttied portionsextending entirely around the window frame, as indicated in Fig. 3 whichis a longitudinal section, and Fig. 6 which is-a trans- 25 versesection, whereby the V-shaped Weatherstrip element 30 and the windowframe and its puttied portion 26 cooperate in forming a weatherproofclosure for the'window opening.

The operation of the invention will be under- 30 stood by referring toFigs. 1, 4, 6 and 7. The sash, which is intended for basement windows,is mounted on the spring hinges illustrated in Figs.

1 and 6 which is swingable inwardly as shown in Fig. 7. The screen 33 ispermanently held in place by the frame members 3I and 29, the member 3|being bolted to the member 29 which latter member is also welded orafiixed to the side jambs 3 and 4 of the window frame, by welding 3 I,as shown in Fig. 3, at each end of the window frame. The V-shaped orinturned Weatherstrip extension 30 of member 29 seats snugly against theputtied portion 26 to seal the ends of the window frame from theentrance of rain. The depending Weatherstrip 28, as shown in Fig. 6,which extends longitudinally of head jamb I and which is interposedbetween the screen frame member 29 and the top rail I2 of the sashframe, prevents entrance of water at the top of the sash. The curvedWeatherstrip 8 welded longitudinally of the sill 2 and on which thecurved Weatherstrip guard extending along the bottom of the window sashsnugly seats forms an effective closure against the admission of waterat the bottom of the window frame and window sash. The outwardly curvedshape of the portion 1 of the sill tends to shed water.

The operation of the locking bolts or catches I 8 which are positionedfor engagement in the apertures 23 in the side jambs of the windowopening will be obvious by reference to Fig. 4, which also clearlyillustrates the pivoted cam or catch operating member [9. The windowframe, as shown in Figs. 3 and 6 of the drawings, is substantallyU-shaped in cross section.

As shown in Fig. 3, the side lambs 3 and l of the window frame areprovided with brick and tile stays which are used in securing the windowframe in the wall of the building in which this basement window sash ismounted.

What I claim is:

1. In a weatherproof metal sash, the combination of a sash frameL-shaped in cross section, a pane mounted in said sash frame, puttyfilling the L-shaped portions of said sash frame securing said pane inthe sash frame, a metal window frame within which the sash frame ishingedly mounted, weatherstrips V-shaped in cross section and welded onthe sides to the window frame, said weatherstrips having their innermembers seated snugly against the said putty to seal the ends of thewindow frame.

2. In a weatherproof metal sash, the combination of a sash frameL-shaped in cross section, a pane mounted in said sash frame, puttyextending across the L-shaped ends of said sash frame securing said panein the sash frame, a metal window frame within which the sash frame ishingedly mounted, a depending Weatherstrip welded on the head jamb ofthe window frame to make a weatherproof frame, weatherstrips V- shapedin cross section welded on the sides of the window frame and seatingsnugly against the aforesaid putty.
